Experimental evaluation of a coherent DPSK-BPSK Long-Reach PON

This article presents a DPSK-BPSK coherent LR-PON employed for sending data at 10Gb/s using homodyne and heterodyne reception. Receiver sensitivities of -21dBm, for homodyne, and -20dBm, for heterodyne, where achieved for a BER of 10−3.
